“…When activated by sudden changes in the subject's environment, ACC may operate as a ''supervisory attentional system,'' able to promote the activity of the dorsolateral PFC for the integration of plans, instructions, stimulus processing, decision making, short-term memory updating, and response control [Shallice, 1988]. In this sense, the present results extend previous evidence suggesting that the directed attention is organized at the level of a distributed large-scale network revolving around three cortical epicentres (or local networks)-ACC, dorsolateral PFC, and posterior parietal cortex [Mesulam, 1981[Mesulam, , 1990[Mesulam, , 1999Nebel et al, 2005], which would provide a slightly different but interactive and complementary type of top-down attentional functions [Corbetta and Shulman, 2002;Fan et al, 2005;Kondo et al, 2004;Konrad et al, 2005;Luks et al, 2002;MacDonald et al, 2000;Milham et al, 2003].…”

Abstract:What is the neural substrate of our capability to properly react to changes in the environment? It can be hypothesized that the anterior cingulate cortex (ACC) manages repetitive stimuli in routine conditions and alerts the dorsolateral prefrontal cortex (PFC) when stimulation unexpectedly changes. To provide evidence in favor of this hypothesis, intracerebral stereoelectroencephalographic (SEEG) data were recorded from the anterior cingulate and dorsolateral PFC of eight epileptic patients in a standard visual oddball task during presurgical monitoring. Two types of stimuli (200 ms duration) such as the letters O (frequent stimuli; 80% of probability) and X (rare stimuli) were presented in random order, with an interstimulus interval between 2 and 5 s. Subjects had to mentally count the rare (target) stimuli and to press a button with their dominant hand as quickly and accurately as possible. EEG frequency bands of interest were y (4-8 Hz), a (8-12 Hz), b (14-30 Hz), and g (30-45 Hz). The directionality of the information flux within the EEG rhythms was indexed by a directed transfer function (DTF). The results showed that compared with the frequent stimuli, the target stimuli induced a statistically significant increase of DTF values from the anterior cingulate to the dorsolateral PFC at the y rhythms (P < 0.01). These results provide support to the hypothesis that ACC directly or indirectly affects the oscillatory activity of dorsolateral PFC by a selective frequency code under typical oddball conditions.

“…is easily interpreted, that is, momentum conservation tends to emit two neutrons in opposite directions. These trends have preliminarily been confirmed to be consistent with our own kinematics analysis results based on the measured result of α emission spectrum by Kondo et al [5]. The present ADDX is anyhow the first measured result over the world.…”

Abstract. The angle-correlated energy differential cross-section for 9 Be(n,2n) reaction has been measured with the coincidence detection technique and a pencil-beam DT neutron source of FNS, JAEA. Neutron energy spectra of two emitted neutrons were separately obtained as azimuthal-and axial-angle differential value, which is called TDX. From the measured TDX, double-angle differential cross sections, ADDX, angular differential cross section, ADX, and total cross section, TOX, were deduced. In the TDX, a characteristic energy spectrum for beryllium was seen. The azimuthal ADDX unexpectedly showed a 180 deg. symmetrical spectrum, not a flat one. From the result of TOX, JENDL-3.3 and ENDF/B-VI showed a little underestimation by around 10%.

“…Therefore, if an individual difference is rooted in motion assimilation, which might originate in the MT, the neurotransmitter concentration in the MT could be correlated with an individual difference. Third, an individual difference in cognitive functions, such as an attention allocation or a top-down judgement [33,34], will result in differences in motion perception between the participants. Alternatively, it could be possible that a mechanism at a level higher than the MT is involved in the induction of motion assimilation, for which a function of the attentional mechanism would be crucial [12].…”

One contribution of 15 to a theme issue 'Auditory and visual scene analysis'. Recent studies have shown that interindividual variability can be a rich source of information regarding the mechanism of human visual perception. In this study, we examined the mechanisms underlying interindividual variability in the perception of visual motion, one of the fundamental components of visual scene analysis, by measuring neurotransmitter concentrations using magnetic resonance spectroscopy. First, by psychophysically examining two types of motion phenomena-motion assimilation and contrast-we found that, following the presentation of the same stimulus, some participants perceived motion assimilation, while others perceived motion contrast. Furthermore, we found that the concentration of the excitatory neurotransmitter glutamate-glutamine (Glx) in the dorsolateral prefrontal cortex (Brodmann area 46) was positively correlated with the participant's tendency to motion assimilation over motion contrast; however, this effect was not observed in the visual areas. The concentration of the inhibitory neurotransmitter g-aminobutyric acid had only a weak effect compared with that of Glx. We conclude that excitatory process in the suprasensory area is important for an individual's tendency to determine antagonistically perceived visual motion phenomena.This article is part of the themed issue 'Auditory and visual scene analysis'.
